A new Postman is here: Collection Runner
Collection Runner now runs and automates workflows that include GraphQL, gRPC, and HTTP requests, with support for additional protocols coming soon. Plus, teams can now execute the same collections locally and in CI.
With Postman's AI capabilities, automated tests for these protocols can be generated, updated, and maintained by agents, then executed directly in Collection Runner. Teams can also use Postman AI to debug failed runs and identify what caused the failure.
Collection Runner
Run collections across data and environments without the hassle of inconsistent runs or endless clicking, so you move faster and your team stays in sync.
Run any workflow
From simple requests to multi-step scenarios, Collection Runner provides end-to-end execution. No more testing endpoints one by one.
Automate runs anywhere
Trigger runs manually, on a schedule, from the CLI, or in CI/CD so your APIs are tested before issues reach production.
Validate in every environment
Keep tests consistent by swapping environments, not rewriting requests. Catch environment-specific issues before they reach users.
Run complex workflows with ease
Test full collections that mirror real-world usage. From simple chains to multi-step workflows, Collection Runner keeps requests in order, giving you confidence that your API works from start to finish.
Test across environments
Test across dev, staging, and production without rewriting. Collection Runner uses environment variables to keep runs consistent and reliable everywhere.
Data-driven testing at scale
Upload CSV or JSON files to run workflows against hundreds of inputs. Quickly uncover edge cases, validate performance, and strengthen API reliability without extra setup.
Simulate real-world load
Test traffic with virtual users, track key metrics in real time, and spot bottlenecks before they reach production.
For API development teams
Scale with collections
Collection Runner lets you test and validate entire workflows at scale, while collections keep those workflows organized and reusable across your team.
- Stay consistent across environments: Use environment variables to run the same workflow in dev, staging, and production without rewriting requests.
- Reuse and share workflows: Collections provide a single source of truth.
- Enable safe feedback loops: Simulate real-world usage in Collection Runner to validate reliability under load without impacting live systems.
Postman Collections have transformed API testing, enabling us to experiment quickly and efficiently when developing new features or implementing changes."Benny Yamagata, Senior Software Engineer, NetDocuments
